Gabion mesh

Gabion is a mesh product widely used in engineering fields.

1. Material composition

Gabion is made of high-quality low-carbon steel wire or PVC-coated steel wire with corrosion resistance, high strength, wear resistance, and ductility, and is woven by machine into a hexagonal mesh in the shape of a honeycomb. This mesh structure is flexible and easy to assemble and process.

2. Product form

Gabion box: In general, the gabion box is a rectangular box assembled from 4 pieces of gabion nets, one large and three small. The large piece of gabion net is bent into the column of the box, and the three small pieces of gabion net are placed at both ends of the box and used as the middle partition. Because the gabion net is flexible to assemble, it can also be assembled into other shapes according to the actual application scenario requirements.

Gabion pad: A box structure made of gabion net cut and bent. Unlike the gabion box, the thickness of the gabion pad is generally about 15cm~50cm, the height is relatively low, and the structure is flatter and wider. Generally, the diameter of the steel wire around the edges of each mesh plate of the gabion mesh mat is thicker than that of the steel wire in the middle mesh mat, in order to increase the strength of the overall structure of the gabion mesh mat.

3. Main features

Good structural flexibility: The gabion mesh structure has good flexibility and can quickly adapt to the surrounding environment without being damaged.

Strong corrosion resistance: The gabion mesh adopts the hot-dip aluminum-zinc process and the resin film coating process. The surface coating of the steel wire is more stable, which can effectively reduce the oxidation of the mesh wire. It has the characteristics of corrosion resistance, anti-static, anti-aging, and anti-oxidation, and has a longer service life.

Simple construction: The gabion mesh process can be produced in a factory according to the design intention to produce semi-finished products. The construction site is assembled and finalized according to the design drawing, and then laid on the prepared soil slope or the excavated foundation pit, and the filling material is poured in and the cover net is added. It is easy to operate, less affected by the climate, and suitable for mechanized operation, which can not only ensure the construction quality but also speed up the progress of the project.

Good water permeability: The retaining wall and slope protection built with mesh boxes are filled with loose materials with more pores, which is conducive to the discharge of pore water in the backfill and the soil layer under the slope protection. Once the surface water infiltrates into the soil, it can be discharged quickly through the masonry, effectively lowering the groundwater level, thereby reducing the groundwater pressure behind the wall and under the slope.

Stability and strong overall function: The gabion mesh is a double-twisted grid structure woven by special machinery. Local damage will not cause overall damage to the box cage. The gabion mesh material has moderate deformation characteristics, connecting the entire project into a whole without seams. Even if there is uneven subsidence, the overall structure will not produce cracks or serious problems.

Good landscape effect: The easy combination of the gabion mesh structure and the diversity of colors can provide us with a variety of structural designs to meet the landscape requirements of different regions. At the same time, combined with planting lawns and flowers and trees, we will be presented with a green retaining wall or slope protection.

Strong anti-scouring ability: The gabion mesh structure is used as a slope protection or retaining wall project on a river with a high flow rate, and has strong anti-scouring ability. According to relevant experiments, the anti-scouring coefficient of the gabion mesh structure is twice the anti-scouring coefficient of the general riprap protection project. Affected by the scouring of water flow, even if the blocks in the gabion mesh cushion are displaced, the deformed box cage structure will produce a new balance, and the overall integrity will not be destroyed.

4. Main uses

Due to its unique performance and structural characteristics, gabion mesh is widely used in many fields:

Water conservancy projects: used to prevent soil erosion, purify water sources, strengthen dams and river embankments, etc.

Traffic engineering: used for high-speed guardrails, slope protection, and beautification belts on both sides of the highway, etc.

Construction engineering: used for gymnasium fences, retaining walls, and large slope support, etc.

Crafts production: using its unique mesh structure and aesthetics to make various crafts.

Gabion mesh is a structural material with excellent performance and wide application, playing an important role in many engineering fields.
